Abstract
A computer implemented method includes receiving partially created software defined network (SDN) policy state information at a backup software defined network (SDN) appliance in response to the sending of a synchronize packet to establish a connection. The state information corresponds to a state of the connection between two endpoints that include a first active SDN appliance and a second active SDN appliance. A replica of the SDN policy state information is saved at the backup SDN appliance. An update to the SDN policy state information is received in response to the sending of an acknowledgement packet. The replica of the SDN policy state information updated at the backup SDN appliance to enable the backup SDN to transition to active.
